Headline Hierarchy
Globally adjust headline levels.
Description
This utility makes use of Allen’s HTML Ninja Technique and provides a simple way to change the hierarchy of headlines.
This is useful if you you don’t want authors to take care of headline levels (h1, h2, h3) when creating entries. Using this templates authors can always start this a h1 and you can adjust the output to the needed level.
